What does someone have to do if he/she masturbate while in fast state during Ramadan?

A sister masturbates as a habit right from childhood, even during Ramadan. She can't control herself even if she didn't have the intention of doing it, even though she knows recently (like 2 years ago) that it's haraam, it has been going on for over 10 years. 1. Does she need to repay up her Ramadan fast or not, that no matter how hard she tries to avoid this, yet proves abortive. 2. Will ALLAH accept her fasting whenever she did the act she continues her fast, that the addiction she can't control it.
